Typically 4-way wiring consists of 18 and 16 gauge wires.

For a 4-way that has all 16 gauge wire you would want the Wesbar 4-Pole Flat Connector # W787264.

The part # HM38138 uses 18 gauge for all wires but the white that uses 16 gauge.

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
